IPC: B01F25/40
Filed: 2021-06-16
Abstract: To suppress generation of gypsum scale in a device for mixing gypsum granular material and gypsum slurry derived from a waste gypsum board.CONSTITUTION: A mixing method for gypsum granular material and gypsum slurry derived from waste gypsum boards comprises: feeding hemihydrate and/or anhydrous type III gypsum granular material derived from waste gypsum boards into a flow passage of an aqueous gypsum slurry containing gypsum dihydrate; mixing the gypsum granular material; and supplying the gypsum slurry to a precipitation tank. The method supplies the gypsum slurry from an inlet of a flow passage, feeds, from above into the gypsum slurry, the hemihydrate and/or anhydrous type III gypsum granular material derived from waste gypsum boards, and after feeding the gypsum granular material, with an upper liquid surface of the gypsum slurry being always exposed to air, causes the gypsum slurry to flow to an outlet of the flow passage. The method causes the gypsum slurry to freely fall from the outlet of the flow passage to feed it into a pipe, and causes the gypsum slurry to collide against a surface on a far side as viewed from the outlet of the pipe, to fall down, or to fall down through a center part of the pipe.SELECTED DRAWING: Figure 2
